I have MacOS Tahoe 26.6.2, and for some reason, I couldn't get the Channels DVR app to update. I uninstalled it thinking I would just reinstall with the latest version, and now it won't install at all. This version of MacOS was released to GA 3 days ago, so the app might still needed to be tested on it, but it's not beta. I did notice that Apple considers it an iPad app and not specific to MacOS. Not sure if that has any impact.
Do you have an ETA for when this will be fixed, assuming it's not an Apple/MacOS restriction?
